ELECTRIC CONNECTOR FiLed;April 20, 1940 2 Sheets-Sheet 2 Patented F.1..-'25. 1941 UNITED STATES PATENT OFFICE 1 Claim.

This invention relates to new and useful improvements in electric connectors and more particularly to an electric cord plug.

The principal object of the present invention is to provide an electric plug of the character stated constructed in such a manner as to contain fuses for the electric circuit in which it is connected.

Another important object of the invention is to provide an electric plug of the fuse element type wherein fuse elements can be removed and replaced whenever desired.

These and othenobjects and advantages of the invention will become apparent to the reader of the following specification.

"" In the drawings:

Figure 1 represents a side elevational view of the plug.

Figure 2 is a side elevational view showing the sections thereof in separated relation.

Figure 3 is an elevational view looking at the prong end of the plug.

Figure 4 is a. longitudinal sectional through the plug.

Figure 5 is a section on the line 5-5 of Figure 4.

Figure 6 is a top plan view of the fuse containing section of the plug.

Figure 7 is an inside elevational view of the cap section of the plug.

Figure 8 is a perspective view of one of the fuse elements. a

Figure 9 is a cross section taken substantially on the line 99 of Figure 4.

Referring to the drawings wherein like numerals designate like parts, it can be seen that the plug consists of the fuse containing section 5 and the cap section 5. The upper portion of the section 5, as shown in Figure 4, is reduced to define a shoulder 1 over which is slippe the apron portion .a. of the cap section 6.

The section 5 has a pair of pockets 8 therein for containing the fuse elements 9 (see Figure 8). Inlaid in the bottom of the section 5 are arcuateshaped metallic members Ill-40 against which the adjacent ends of the fuses 9 abut as shown in 5 Figure 4. Each of these arcuate members is secured to the section 5 by a screw H at one of its ends while its opposite end is provided with an elongated outstanding connector prong |2. These prongs are disposed in spaced parallel relation as 50 suggested in Figures 3 and 4.

As shown in Figure 6, the remaining ends of the pockets 8 are closed by the substantially circular shaped members l3 of current conview ducting material which have the arcuate-shaped tail portions l4 inlaid in the top portion of the section 5. These arcuate-shaped tail portions are secured to the section 5 by screws l5, while at the screw secured end of the tail members H! are the upstanding flanged lugs l6 which are adapted to be engaged by the depending hook members ll on the inside of the cap 8. As shown in Figure 7 these hook members H which are of current conducting material are carried by arcuate-shaped conductor strips l8, each being secured in place to the cap 6 by a binding screw IS. A cord 20 with its conductors 2| is disposed through an opening 22 in the cap 6 and the'conductors 2| are secured by the binding screws I9.

It is a simple matter to partly rotate the cap to disconnect the hooks I! from the lugs It for the I purpose of renewing the fuses 9 or properly con necting the conductors 2| with the binding screws l9. go

It is preferable that the periphery of the cap 6 be knurled or milled as denoted by numeral 23 to facilitate turning thereof.

While the foregoing specification sets forth the invention in specific terms, it is to be understood 25 that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having described the invention, what is claimed 30 as new is:

An electric connector comprising a body, a cap structure for the, body, said-body being rabbeted at one end to define a shoulder against which the cap engages, a pair of contact strips on the rab- 35 beted end of the body, each of said strips having one end anchored to the body and its other end offset from the body, said cap having a pair of contact members of elongated construction at the inner side thereof, each of the said elongated contact members having one end anchored to the cap and its other end offset, said cap structure being rotatable on the shoulder of the body to bring the offset end portions of the contacts of the capinto interlapping engagement with the offset end portions of the contact on the body, said body being provided with a pair of openings therethrough, a fuse in each of the openings, a pair of prongs projecting from the remaining end of the body and having the fuses bearing against the inner ends thereof, the contact on the body being in contact with adjacent end of the fuses.
